1 Claim, (01. 1s9 s2 The present invention relates to new and useful.improvements in lattices for different pur--- poses and has for itsprimary object'to provide,

in a manner as hereafter set forth, a device of,

thischaracter embodying a novel construction, combination andarrangement of parts through the medium of which said devicemay beconveniently adjusted longitudinally to meet various conditions; I

Other objects of the invention'are to provide an extensible lattice ofthe character described which will be comparatively simpleinconstruction, strong, durable, ornamental and attractive in appearanceandwhich may be manufactured at low cost;

All of the foregoing and still further objects 1 and advantages of theinvention will become apparent from a study of the followingspecification; taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout: the several views, and wherein:

Figure l is a view in front elevation of an extensible latticeconstructed in accordance with the present invention, showing the devicein use.

Figure 2 is a view in vertical section, taken substantially on the line22 of Fig. 1.

Figure 3 is a view in horizontal section through the device, the end'portions thereof being broken away. I I

Figure 4 is an enlarged view in elevation of a corner portion of one ofthe frames and the ad jacent parts. v

I Figure 5 is an enlarged elevational view of the lowerinner cornerportion ofthe slidable frame and the adjacent parts.

Figure 6 is 'a planview of one of 'the guides.

Referring nowto the drawings in detail, it

will be seen that the embodiment of the invention which has beenillustrated comprises a pair. of substantially rectangular'frames .I andZ of suitable metal. Theframes l and 2 are similar in construction andare of the cross sectional shape shown to advantage'in Fig. 2 of thedrawings, said frames includingsubstantially. .C-shaped outer portions3having formed integrally therewith spaced, opposed inwardly extendingflanges 4. Mounted in the frames I and 2 are foraminous metallic sheets5. The foraniinous sheets 5 may be of expanded metal. 1

The frames 1 and 2am adjustably'connected for movementtoward or awayfrom each other by a lazy tong 8 which is connected, at its ends, tosaid frames through the medium of clips I.

As illustrated to advantage in Fig. 4 of the drawings, the uppermostclips Tare permanently fixed on the portions 3 of the frames I and 2 bywelding, as at 8. The lowermost clips I are slidable on the frames I and2, as shown to advantage in Fig. 5 of the drawings.

Mounted on the top and bottom of the frame land projecting horizontallytherefrom above and below the lazy tong 6 is a pair of guides 9 in whichthe frame 2, is slidable. The guides 9 terminate in substantiallyC-shaped, right angularly extending end portions Ill and II whichaccommodate the frames I and 2, respectively. As also shown to advantagein Fig. 4 of the drawings, the end portions II] of the guides 9 arefixed to the top and bottom of the frame I by Weldirig,

as at I2. The frame 2 is'slidable in the other end portions II of theguides 9.

g It 'will thus be seen that a lattice has been provided which may beexpeditiously adjusted longitudinally .to meet various conditions. InFig. l of the drawings, the device is shown in use between a pair ofpiers l3. However, it will be understood that the device may be used forany other purposes for whichit may be found adapted and.'desirable, suchas in vents, in concrete or masonry walls. The frame, 2 is slidablelongitudinally in the guides 9 toward or away from the frame I, the lazytong 6 permitting any desired adjustment to be readily made within therange of said lazy tong, of course. i

I It is believed that the many advantages of a adjustable latticeconstructed in accordince with the present invention will be readilyunderstood and although a preferred embodiment of the device is asillustrated and described, it is to be understood that changes in thedetails ofconstruction and in the combination and arrange ment of partsmay be resorted to which will fall of each pair being slidably connectedto its respective frame, a pair of elongated bars, means for firmlyconnecting one end of one bar to the top of the first frame, means forfirmly connects ing one end of the other bar to the lower part of saidfirst frame, the bar connected with the upper end of the first frameextending over the top 2 2,191,566 7 v oflthe lazytong assembly, a clipconnected'to the second frame, the clip-carrying ends of the bars otherend of said last-mentioned bar and slidbeing located adjacent the innerend of the sec ably engaging the top of the second frame, the 0nd.'frame when the lazytong assembly is exbar which is connected with theunder part of the panded. t first frame extending under the lazytongassembly and having a clip fastened to its other v DEWEY O.
